Foreign object monitoring device, foreign object monitoring system and method for electric vehicle wireless charging

Abstract

The invention discloses a foreign body monitoring device, a foreign body monitoring system and method for wireless charging of an electric vehicle. The foreign body monitoring device comprises a beamgenerator, a renderer, an image collector, a horizontal moving movement mechanism, and a first lifting movement mechanism, wherein the beam generator is used for projecting beam to a wireless chargingtransmitter; the renderer is used for displaying the projection picture of the wireless charging transmitter projected by the beam generator; the image collector is arranged on the same side of the beam generator, and used for collecting the image of the projection picture displayed on the renderer; the horizontal moving movement mechanism can drive the beam generator and the image collector to horizontal move relative to the wireless charging transmitter; and the first lifting movement mechanism can drive the renderer to be lifted relative to the wireless charging transmitter. The foreign body monitoring device can detect the foreign body on the wireless charging transmitter and is simple and convenient, the detection efficiency is high, and the safety of wireless charging of the electric vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a foreign object monitoring device, a foreign object monitoring system and a method for wireless charging of an electric vehicle.
